Armitage believes that if dinosaurs have soft tissue in their bones, then something is wrong with the belief system that says the world is billions of years old. (2018) are, in many cases, subsequent steps of a single, unified reaction mechanism, and not separate hypotheses. How to read the Bible in chronological order. Structure of Dinosaur Collagen and the Age But I wanted to show the chemistry behind these ideas, and that it plausibly explains the soft tissues and cells were seeing in, for example, dinosaurs. Since then Schweitzer said, Thats the way science should work. (North Carolina State University, 28 April 2023). At the end of the Cretaceous Period, dinosaurs went extinct. Chronological index. In most cases, microbes feast on a dead animal's soft tissue, destroying it within weeks. Even a polymer shield strong enough to resist microbes would develop cracks. 1995: spectroscopy and chemical analyses of extracts from a T. rex femur suggested preserved proteins, including a form of collagen abundant in modern animal bones. You can't predict when a specific unstable atom, or parent, will decay into a stable atom, or daughter. [14][15][16] Blood-derived porphyrin proteins have also been discovered in a mid Eocene mosquito fossil. Such a thing could hardly happen today, for soft tissue decays rather quickly under any condition. The flood was followed by an ice age during which there were volcanic and glacial impacts. "Geologic Time." document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Scripture index When Mary Schweitzer saw red blood cells in soft dinosaur tissue her supervisor said, Prove to me theyre not. Schweitzer and her colleagues found that dinosaur soft tissue is closely associated with iron nanoparticles in both the T. rex and another soft-tissue specimen from Brachylophosaurus canadensis, a type of duck-billed dinosaur. Mary Schweitzer proposed that iron from blood helped preserve dinosaur tissue for millions of years by crosslinking proteins and acting as an anti-oxidant. A thigh bone from a 70-million-year-old Tyrannosaurus rex has given fossil experts an unexpected treasure: well-preserved soft tissue. Schweitzer and her colleagues first raised this question in 2005, when they found the seemingly impossible: soft tissue preserved inside the leg of an adolescent T. rex unearthed in Montana. Then a blatant assertion is made to sweep away the issue: Because we didnt realize that these processes could come from the same starting place and share a step, the hypotheses have been presented as separate, Anderson says. John Morris from the Institute of Creation Research writes: Indeed, it is hard to imagine how soft tissue could have lasted even 5,000 years or so since the Flood of Noahs day when creationists propose the dinosaur was buried. The earths geological and climatological history has determined the current geomorphological and geological structure of the earth.
